Kewtech KT63DL Multifunction 5-in-1 Tester

The Kewtech KT63DL Multifunction 5-in-1 Tester packs an array of features into a simple, user-friendly system ideal for testing and certifying both domestic and commercial electrical installations. The device is capable of insulation testing up to 1000V with an auto discharge function, auto ranging continuity measurements up to 2000Ω and full no trip Loop testing on all types of RCD. PSC/PFC results are displayed simultaneously with loop impedance and new anti-trip loop testing technology, which when combined with continuous live monitoring, ensures no bangs during testing, including throughout the auto test for RCDs up to 30mA. These results include a low susceptibility to RCD uplift and noise interference for maximum reliability. A ramp test function is also incorporated. 

The KT63DL includes ultra-slim probe tips, which are gold-plated for consistent readings. They are also able to access slimmer terminals. Featuring test leads which auto-null for continuity, the KT63DL can perform mains polarity tests and is fully protected against phase-to-phase connection. An independent hands-free mode controlled by a separate button and built-in instant correct wiring status check improves not only the efficiency of the instrument, but the overall safety of the operator. The IP65-rated casing is lightweight and ergonomic with a tactile interface consisting of easy-press buttons and a single rotary dial for function selection. An end-of-line calibration certificate is included with the KT63DL, completed with an ACC063 3-wire distribution board test lead and soft carrying case.
